4 Claims. I

My invention relates towrapping machines and more particularly to a typeof machine that "will place an outside sheet or wrapper around aquanti-ty of bound pamphlets, magazines, newspapers, or similararticles.

An object of my invention is to provide arlevice that will hold "a stackof sheets or the like, in engagement with one another and in stackedrelation to one another while the wrapping operation is progressing.

Another object of my invention is .to provide .a device that will adjustitself to any height of stack, or any number of sheets.

, .Still another object of y invention is to provide a device that isoperated .by a single actuatmg means.

When preparing a quantity of newspapers,

magazines or the like .for mailing, it is necessary to wrap variedquantities, depending on the yrequi-red number of copies in each bundlebeing wrapped. With the device specified, claimed and illustratedherein, it is only necessary .to place the single sheet of wrappingpaper .or hinder on the bottom conveyor, together with .the desired.quantity of periodicals and newspapers disposed thereon and they willbe conveyed towards the rolls and held in position while they are beingput into a compact, tightlyerolled, wrapped package.

The device is simple in construction, easy to operate, and highlyefiicien-t for the purpose for which it is intended.

Other and further objects of :my invention becomemore apparent as thedescription proceeds when taken in conjunction with the drawing inwhich:

Figure l is .a side elevation :of the assembled device showing thecomponent parts constituting the device.

Figure 2 is a fragmentary view .of the conveyer .arangement, showing astack of papers on the loading end .of the :bottom conveyor.

Figure .3 is a similar view showing the papers rolled into a compactpackage and showing another stack in phantom placed on the conveyorready for wrapping.

Figure 4 is a top viewof the conveyer belt together with the flangedroller at the end pf the bottom conveyer, taken at the line 4-4 inFigure '3, and

Figure 5 is a top view of the top roller on the right in Figure 1.

Similar characters of reference indicate correspond-ing parts throughoutthe several views, and referring now to the same, the characters It),I'll and W portray ,a frame construction which :may consist .of castingsor may be as shown constructed of angle iron or structural steel. vframe has vertical end members II extending upward therefrom, and alsovertical plates shown as H and 11 having angularly disposed slots 43therein. The vertical end members N and the vertical plates I2, areprovided'wi-th bearings 154 and I4" near their upper ends which supportshafts l5 and 15' respectively, on --which -pulleys 16 are rotatablymounted. These pulleys 46 have grooves on their outer periphery tor theengage- .ment of cables I! and W which support weights 18 .on theirfreeends. 7

'There is a main conveyor unit consisting of a plurality of V-ibe'lts 19which are horizontally :disposed over =v-pnlleys 2-0 and 241' spacedapart from one another and mminted on shafts 21 and 21 respectively.These shafts are journalledqin bearings 22 and 22" respeetivelysupported by the vframe member 10'.

There is an idler :roller 28 contacting the lower face of the V- belt'sl 9. This idler roller is journal'led on the upper end of pivot-edlevers '24! mounted on a shaft 25 which is tourna-lled in bearings 26supported on a portion of the frame I'll. IFhe lower depending ends ofthe levers M are provided with springs H which are attached at 28130 thebase of the frame 4H).

There is an auxiliary conveyerunitconsisting or a plurality of V-belts29-supportedbyt7 -belt pulleys 3:0, 31 and 132 which are mounted onshafts 3%,"34 and 35 respectively and spaced apart from one another. Allof these shafts are journalled Withinan auxiliary *frame member shown as38.

The shafts '34 and 35 engage the slots 1'3 in the verticalplates 1 2 andt2" 'arrdhave the other ends of the cables W and W" respectivelyattached "thereto. Obviously, the weights *8 are heavy enough t0 almostcounterbalance the -weigh-t of the assembled auxiliary conveyorunit'thereby permitting its 'up and down movement w i'thlease,when-guided by the slots P3. The shafts l5 and t5" are equipped withadditional "pulleys .37 supporting a cable 38 over a portion of theirouter peripheral surfaces. This cable 38 equalizes and controls evenly,the revolving of the pulleys '16 supporting the cables Hand M. s

'The pulleys 30 are of smaller diameter than the pulleys 3-1, therebycreating an angular sec- 'tion 39 on'the bottom ofthe til-belts 29 topermit the engagement of a stack. of periodicals ready to .be wrapped asshown at 4'0 in Figures and 3 between the belts 1'9 and-the belts -29."The height of the stack 40 will determine the height that-the 3auxiliary conveyer unit willrise when counterbalanced by the weights [8.

The lower surface of the upper V-belt I9 is supported by a roller 4|mounted on a shaft 42, journalled in bearings 43 supported by the angleirons l9 constituting a portion of the frame I0. A motor 44 acting as anactuator for the pulley 45 mounted on the shaft 46 journalled inbearings 4! shown supported by the frame member revolves the pulley bymeans of the belt 48. Other bearings 49 are mounted on the frame memberID and support a shaft 50 on which pulleys 5| and bracket links 52 aremounted, the pulleys 51 being rotated by means. of the belt 53 when thepulleys 54 on the shaft 46 are revolved. There are also shown drivebelts 55 which revolve the shaft 2| to actuate the conveyer belt l9 onthe pulleys 20 and 20".

The links 52 supported by the shaft5n also support a shaft 56 at theirupper end, and pulleys 51 are mounted thereon and revolved by means of abelt 58 over the pulleys 5|. Another set of link members 59 supported bythe shaft 56 act as a support for pulleys 60 which are .mounted on theshaft Bl which is supported on the frame 3-6 to revolve the top roller62 in the wrapping operation. The roller 62 consists of a plurality ofdiscs spaced apart from one another and is free to move up and down withthe auxiliary conveyer supported within the frame structure 35.

The shaft 46 also supports a frame 53 which acts as a support for theroller 64 journalled on the shaft 65 and revolved by means of the belt66 over the pulleys 54 and =61 respectively. The frame 53 is supportedat 68 by a piston rod 69 forming a part of a piston and cylinderassembly Hi which is provided with a resilient member H. The cylinder inis hingedly attached at 12 and is actuated by a source of pneumaticpressure (not shown) through the tubular member 13.

In operation, the device functions as follows: The magazines or papersto be wrapped are placed on a piece of wrapping paper disposed onto thetop surface of the belts l9 and as the belts [9 travel in the directionas indicated by the arrows in Figure 3, the papers will be conveyedtowards the angular portion 39 of the auxiliary conveyer, which beltsalso travel in the same direction, and as the newspapers or magazinesare carried between the belts l9 and 29 towards the rollers 62 and 64,they will be caused to assume a cylindrical contour as shown at 14 inFigure 3, and as the wrapping paper forming the outer wrapper for therolled articles is provided with a strip of glue at its open end, therevolving of the rollers 52 and 64 together with the pulleys 32 on whichthe belt 29 are disposed will cause the entire unit to assume acylindrical contour, and when the pneumatic arrangement of the assemblyIn is put into operation, the piston will be drawn down into thecylinder causing the roller 64 to move downward in its path therebyreleasing the rolled periodicals such as the papers or magazines shownat 14.

In the chosen embodiments of my invention, there are many features thatare heretofore disclosed in the prior art, and although I have shown aspecific arrangement of the component parts constituting the device, Iam fully cognizant of the fact that these parts may vary in form andcontour and even in arrangement to some extent, without departing fromthe spirit of my invention or the scope of the appended claims l Havingthus described my invention, what I claim and desire to secure byLetters Patent in the United States is:
